Marek Fila (KAMŠ FMFI UK):
A Gagliardo-Nirenberg-type inequality and its applications
to decay estimates for solutions of a degenerate parabolic equation


Abstract:
We discuss a Gagliardo-Nirenberg-type inequality for functions with fast decay.
We use this inequality to derive upper bounds for the decay rates of solutions
of a degenerate parabolic equation. Moreover, we show that these upper bounds,
hence also the Gagliardo-Nirenberg-type inequality, are sharp in an appropriate sense.
This is a joint work with Michael Winkler.
